  • the thread intended for the screw bolt in the head part of the modular joint prosthesis total length of the existing cylindrical channel.
  • a metric thread is provided at the end part.
  • the thread of the threaded hole in the head part is less Pitch as the thread at the proximal end of the end part and thereby facilitates the generation of the Loosen the fixed conical connector required Compressive force by the bolt.
  • the proximal end of the threaded bore provided in the end part a recess, which is convenient as arranged symmetrically to the longitudinal axis of the bore Chamfer is formed.
  • the free end also is chamfered at the same angle when supporting on the proximal end of the end part not with the Thread of the threaded hole provided in this area can come into active contact.
  • This will create to loosen the conical connector between the head and shaft part required compressive force a deformation avoided the first threads.
  • a deformed one Thread would screw the tie rod in again the proximal end of the end portion after fitting or replacement of the headboard impossible.
  • the modular joint prosthesis 1 shown in FIG. 1 consists of a shaft part 2 and a head part 3, each of which has a profile in the longitudinal direction.
  • the head part 3 carries the articulation means designed as a bone screw 3.1, through which the connection of the joint prosthesis 1 with the Hip joint can be produced.
  • the longitudinal axes of the hinge connection element 3.1 and of the prosthesis shaft 1 enclose an angle of approximately 135 °.
  • the connection between the head part 3 and the joint connection element 3.1 takes place both form and a force fit.
  • the sub-elements 2 and 3 of the shaft 1 are by means of a conical connector 10 lying on the same axis and pivotally connected to each other.
  • a tie rod (not shown) is provided to prevent axial loosening, which through the channel 5 formed as a threaded bore of the head part 3 guided and in the formed as a threaded bore 6 proximal area of the Shaft part 2 provided channel 4 is screwed. The screwing takes place so far that the proximal end of the tie rod is supported in the recess 7 and the individual parts 2 and 3 of the modular joint prosthesis 1 axially against one another are moved until the conical connector 10 has the desired strength having.
  • the conical plug connection 10 In order to be able to change the position of the head part 3 with the articulation connection element 3.1 with respect to the shaft part 2 by pivoting or to replace the head part 3, the conical plug connection 10 must be released again. After loosening and unscrewing the tie rod (not shown), a screw bolt (also not shown) is screwed into the threaded bore 5 of the head part 3.
  • the screw bolt Since the diameter D 1 of the threaded bore 5 in the head part 3 has a greater value than the diameter D 2 of the proximal, threaded portion 6 of the central bore 4 of the shaft part 2, the screw bolt is supported on a surface dimension by the diameter -Difference D 1 - D 2 defined circular ring on the top surface 8 of the proximal end of the head part 3, which is designed as a truncated cone, and is thus able to generate an axially directed compressive force.
  • This force releases the conical plug connection 10, which is very firm due to the action of the tie rod, and enables the joint prosthesis 1 to be adapted to changed physical conditions of a patient in a convenient manner.
  • FIGS 2 and 3 are advantageous embodiments of hinge connection elements 3.1, 3.2 shown schematically as a partial section.
  • Thread 18 facing away from the sleeve-shaped end of the bone screw 3.1 as well the cylindrical hollow pin of the ball-and-socket joint joint element 17 3.2 are provided with a slot 13.
  • the walls of the Slot 13 are through a (not shown) bolt, which - in the threaded bore 15 screwed - on the wall of the conical recess 14 supports, spreadable, so that there is an increase in diameter.
  • the related on the longitudinal axes 12.1 and 12.2 of the joint connecting elements 3.1 and 3.2 inclined bore 16 allows the operation of the (not shown) Tie rod or screw bolt (not shown) for connecting or Separate the individual parts 2 and 3 of the modular joint prosthesis 1.
  • the detail E shown in FIG. 4 according to FIG. 1 shows an advantageous one Development of the invention.
  • a chamfer trained recess 11 is provided at the proximal end of the threaded hole as a chamfer trained recess 11 is provided.
  • the inclination of the flanks 12 is 45 ° with respect to the longitudinal axis 11 and corresponds to the slope of the bevel on Threaded end of the bolt (not shown). This can be an optimal Force input into the end part 2 to loosen the conical connector 10 between end part 2 and head part 3 with relatively little force enable.
  • the grading of the thread diameter according to the invention can also between different successive elements may be provided. This makes it possible, for example, not only to separate - if desired between the head part and the shaft part following in the direction distally, but also between parts of the shaft. For a targeted "Dialing" a connection to disconnect would then have to towards the head end a gradually increasing thread diameter can be selected, whose external thread comes into engagement with the internal thread, which is in the shaft element located on the proximal side of the intended separation point located. He then leans on the edge with the edge of his end the hole of the distally adjacent element and separates the selected one Connection.
